Abstract

Improvement in pistons and especially in those with oleopneumatic suspension, characterized in that the rubbing part is made up of an elastic slice (17) supported by the piston rod (3) and which has a diameter greater than that of the cylinder bore in the free state, so that a gasket provided with a lip (19) oriented towards the volume where the greatest pressure prevails is formed against the cylinder wall, this slice remaining pressed against a cuvette-shaped part (11) supported by the stem, preferably presenting a lateral surface of a generally frusto-conical shape (16) and a maximum diameter compatible with the clearance necessary to allow the articulation, inside the cylinder, of the bowl attached to the stem.
